Nurture and Object of the Invention.

lt relates to that class of shoes in which the soie is grooved or channeled upon its inner or flesh side, in such manner as to form a lip or rib, to which the upper is sewed while the shoe is wrong side out, and consists in lasting the shoe inside out, then removing it from the last, then sewing it on a machine, and afterwards turning it; the object being to make better' machine-sewed work than has heretofore been done, and to do the same in an economical rnanner, foithe following reasons, viz:

The sole of the shoe being in temper at the time of sewing, the tension of a sewing-machine can act more readily and eifect-ively when the last has been withdrawn.

The feed-mechanism eau also beso arranged that, when the last has been removed, less skilled labor' is .required to manipulate the shoe while' in the process of being sewed by machinery.

Description of the Accompanying Drawings.

Figure 1 is a perspective view lof a shoe. Figure 2 is a plan, showing the bottom of the shoe as it appears before being turned.

Figure 3 shows a part ofthe sole and upper in section.

turned and finished in the usual manner.

In temporarily securing the upper'to the sole bethre removing the last, usually prefer the following method-that is, attaching the upper to Vthe lip or rib ou the sole by means ofsha-rp pinsv or pegs, which pass through said lip, as represented iu the drawings,

but wliielrdo not puncture the outer face or bottomk of the sole.

I'Aelaim as my invention-f- The 'herein-described method of making a turned shoe having a sole ,which has been channeled or grooved upon its inner or .flesh side, to wit, by attaching the upper to the sole in the manner herein described, so that the-last can be removedbefore sewing, then. re- 7'ooving the last, sewing, and turning, substantially as set forth.
